SPECIFICATION forming part of Letters Patent No. 284,836, dated September 11,1883.

Application filed March 12. 1883. (No model.)

.to make and use the same, reference being bad to the accompanying drawings, and to the letters or figures of reference marked thereon, which form a part of this specification;

My invention relates to improvements in self-closing gates.

My invention relates to that class of auto matic or self-closing gates which are operated by the wheel of the vehicle on one side of the roadway only, the connection with the gatesection on the opposite side being made by rods extending under the gate across the roadway; and it consists in the parts which will be hereinafter described, and pointed out in the claims.

My invention applies to gates made in two sections and hinged to opposite gate-posts.

Figure 1 is a perspective view of my im proved self-closing gate, the view representing a double or two-section gate. Fig.2 is a view of the adjustable pieces connecting the end of the pull-rods with the lever on the wheel-iron. Fig. 3 is a view ofthe four-armed plate or spider in perspective, the ends of the rods operating the gate from either side being shown in connection therewith. Fig. 4 is a top view of the upper hinge of the gate and its connections. Fig. 5. is a vertical section through line 00, Fig. 4. Fig. 6 is a view from the under side of the devices shown in Fig. 4. Fig. 7 is a perspective view of the lower hinge and its connections with the gate and gate post.

In the drawings, A is the gate, which is made in two sections, Fand G, hinged to their respective posts on opposite sides of the road way.

The top hinge consists, first, of a large flat plate, B, inadewith an opening of quadrant shape, a, within which the crank end 6 on the upper end of the pintle-rod h operates. This hinge is constructed in such manner as to stop or lock the gate, both when open and when closed.

It may be seen in Fig. 4 that the plate B is attached to the side of the post p and projects out some distance from the post. At the point where the pintle-rod extends through it there is a downwardly-proj ecting part of horseshoe shape, 0, in which the. pintle-rod is held in position by a pin, (See the view of the under side, Fig. 6.) The crank h extends at right angles to the rod, and as the rod rotates by the operation of the gate in opening and closing, the crank h passes through the open space a till the end 0 comes in contact with either side of the same, bringing the gate to a complete stop. The end 6, extending up through opening a,is pivoted in the inner end of a short bar or lever, b, which latter is in turn pivoted to a bolt, d, about two-thirds its length from c. The other end of bar I) has the section 0 of the hinge attached to the stile@' of the gate pivoted in it by a hook, j.

In addition to the stop formed by the sides of the opening a,which arrest the movement of the end 6 of crank h, there are provided external notches, f'and f, on the outside of the plate, which also form stops for the hook end j of the section 0, attached to the gatestile 1'. By means of the two stops the gate is held firmly when either open or closed.

The lower hinge, O, is constructed with a main plate, k, of angular shape, extending around one of the inner angles of the gate-post. The upper lug of this plate extends out in line with the diagonal angles of the post, and has vertical slot therein parallel with its sides.

The bar 70 is by preference placed upon the top of plate k, and has a bolt, Z, extending down through the crossed slots in the two sections. The outer end of bar It" is pivoted to the pintle-rod. This lower hingeiforms the means for adjusting the gate in any required direction, and it can be made to swing clear and to operate by means of the connecting devices when a carriage passes over the wheelirons, no matter how much the post 1) may sag in any direction.

The bar m, which extends from the gate-stile hooked the rods a and a, extending from the wheel-irons thereto upon either side of the gate. "The other two arms, q q, of the plateD are bent downward, to allow them to pass under the rods to u, where they connect with the straight arms (1 (1 when the plate D is operated. Two rods, 17 and 1;, connect with the arms q q, and these cross each other as they extend across the roadway under the gate and connect with a cross-bar, D, on the lower end of a similar pintle-r'od, h, which pivots the hingesof the gate-section G on the opposite side. The cross bar D has its ends bent down similarly to the bent arms 9 of the plate D, to allow the rods 1) and o to operate easily. They are provided with adjustable connections near the bar I), as seen in Fig. 1.

The two upper hinges are alike, as are also the two lower ones, though the connection at the lower end of the pintle-rod differs from the one where the side rods connect with the wheelirons, and which is operated by the latter. \Vhen the wheel of the vehicle strikes the wheelirons, the rods u and a move in the direction of the arrows, moving the cross-rods, which connect with plates 1) also in the direction of the arrows seen near them.

It will be noticed by reference to these points that the gate is operated by a pull-and-push movement.

Attached to the outer part of the journal of the wheel-iron s is a cross-lever, a, which is straight and tapering toward either end. This is rigidly attached in the middle to the extended end of wheel-iron s, and pivoted to each of its two opposite ends is a cast forkpiece, 0, which straddles the end of lever n and is pivoted thereto by a bolt. Its fork p is cleft deep enough to give freedom of movement to the rods to and a in their movements. The short cast fork-pieces 0 are slotted longitudinally by a slot, 0, and the pieces 0' 011 the connecting ends of the rods, which unite with them, are provided with a bolt-hole and are made adjustable upon the pieces 0. Both are serrated on their inside or meeting faces, r, so as to prevent any danger of endwise movement in case the bolt uniting them should work loose.

The wheel-iron s is pivoted in the usual manner. It is indicated in connection with the rod-connections, cross-lever, &c., as E in Figs. 1 and 2.

Besides the adjustment of the gate to the post by the lower hinge, C, it can also be used to give a quicker or slower movement to the gate, in connection with the adjustment seen at the points near the wheel-irons.

In operating the gate, as the vehicle-wheel strikes the arch of the wheel-ironin approaching the gate, the iron is thrown down and the lower endof cross-lever n pulls rod a, turning the four-armed plate D to the left, and this, as it is rotated, turns the pintle-rod h in the same direction, the cross-rods o and o giving a reverse movement to the pintle-rod of the gate-section G, (which turns to the right,) and moving the two gate-sections apart until they are arrested by the stops upon the plate B, before described, and seen in the detail figures 4 and 5. In opening, each gate is lifted a little at the front or inner end by the opera tion of the crank end of the pintle-rod, which, as it turns, throws the rear or hinged end of each gate-section alittle out of line with the post, giving it (the gate) a slight twist, which operation facilitates both the opening and closing of the sections.

I am aware that gates operated by the wheel of a vehicle have been made with disks and rods connected therewith on the lower end of the pintle-rod; but I do not claim them.

I am not aware that automatic gates have been constructed with pintle rods having cranks thereon, applied as shown, or having the stops and hinge adjustments seen in my device.

I claim as my invention- 1. The combination, in a gate, of the hingeplate B, provided with the opening a and stops f f, the pivoted bar 1), plate 0, having hook j, and pintle-rods h, substantially as described, and for the purposes set forth.

2. The combination, in agate, of wheel-iron s, the four-armed plate D, having two of its arms bent downward, the cross-bar D, and the rods u u and v o, substantially as described, and for the purposes set forth.

3. The combination, in a gate, of the slotted plate k, slotted bar k, bolt Z, rod 71, and plate m, substantially as described, and for the purposes set forth.

4. In a gate, the plate 13, having stops ff and opening a, pivoted bar I), and plate 0, having hook j, in combination with the rod 71, having arm h and end a, the slotted plate k, slotted bar It, bolt Z, and plate m, substantially as described, and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.
